Suppose you are traveling on a highway at 35 m/s west. seven seconds later you are traveling 20 m/s northwest. what the magnitude of your acceleration in m/s2? what was the direction of your acceleration to the nearest tenth?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
